RAYMOND KAVSE'N ATTORNEY United States Patent I 3,402,502MULTIPLE BUBBLE BLOWING DEVICE Raymond Kaysen, 1341 N. Mascher St.,Philadelphia, Pa. 19122 Filed Sept. 17, 1965, Ser. No. 488,189 r 2Claims. (Cl. 46-6) 'ABSTRACT OF THE DISCLOSURE This invention relates toa bubble blowing device and more particularly to a device which permitsthe blowing of a multitude of small bubbles within a single largerbubble.

The principal object of the present invention is to provide a multiplebubble blowing device that is simple and easy to operate and is positivein its operation.

A further object of the present invention is to provide a multiplebubble blowing device that is simple and in expensive to construct andwhich presents an attractive appearance.

A further object of the present invention is to provide a multiplebubble blowing device that can be molded of synthetic plastic material.

Other objects and advantageous features of the invention will beapparent from the description and claims.

The nature and characteristic features of the invention will be morereadily understood from the following description taken in connectionwith the accompanying drawings forming part thereof, in which:

FIGURE 1 is a view in perspective showing a multiple bubble blowingdevice in accordance with the invention;

FIG. 2 is a vertical sectional view taken approximately on the line 2-2of FIG. 1 showing the device in one operating position;

FIG. 3 is a fragmentary view similar to FIG. 2 showing the device inanother operating position and;

FIG. 4 is a vertical sectional view taken approximately on the line 44of FIG. 3.

It should, of course, be understood that the description and drawingsherein are illustrative merely, and that various modifications andchanges can be made in the structure disclosed without departing fromthe spirit of the invention.

Like numerals refer to like parts throughout the several views.

Referring now more particularly to the drawings in which the device isillustrated, the multiple bubble blowing device includes an outertapered cylindrical wall 10, providing a shell, an inner cylindricalshell assembly 11 and valve assembly 12.

The outer wall can be provided with radial fins 14 on its outermostsurface 15 extending lengthwise of the wall 10 as desired, the finsgiving an attractive appearance to the device and facilitating theholding and manipulation of the device. The wall 10 tapers inwardly atone end as at 10' and the taper terminates at a mouthpiece 16 which isshown as being of relatively straight cylindrical shape. The wall 10, atthe opposite end of the mouthpiece 16, has a flat rim 20 which is at a90 angle to a horizontal plane passing through the end of the wall 10and which rim 20 extends outwardly around the periphery of the wall 10.The rim 20 terminates at an inside surface 21 of the wall 10 and has aface 22 which extends outwards of the surface 15 andterminates at anedge 23. a r

The inner cylindrical shell assembly 11 has a rear inner tube 13 whichextends slightly more than one half the length of the outer wall 10 andat one end is integral with the wall portion 10' at a junction 25. Asiren or whistle 26 of conventional type can be provided forinsertion inthe tube 13 at a section 28. The tube 13 terminates at the end oppositeto the mouthpiece 16 at a front edge 30.

The valve assembly 12 extends into the tube 13, and has an actuating arm31, hollow cylindrical portion 32 with slots 33 near its outer end, andclosing end cap 34. The end cap 34 has a rim 35 with an inner end face36.

The arm 31 of the valve assembly 12 is slidably mounted and retained ina slot 17 in the outer wall 10, which slot 17 permits of limitedmovement of the arm 31.

An additional front inner shell 40 is provided having an inwardlyextending rim 41 which provides a stop for the rim 35. The rim 35 is oflesser diameter than the interior of the shell 40 to permit of thepassage of air along its periphery when the rim 35 is moved away fromthe rim 41.

The inner shell 40 at its outer end has an end rim 42.

The end rim 42 is flat and at a angle to the outside of the shell 40 andhas a face 47 which extends inwardly andterminates at an opening 46which is preferably concentric with the opening 21. The opening 46 inthe shell 40 can be of any suitable size and as explained below toobtain bubbles of a desired diameter. The face 47 is preferably in thesame plane as the face 22. Inside of the inner surface 21 of the outerwall 10 reinforcing fins 50 are provided which are integral with thisinside surface and extend inwardly and along the shell 40 in integralengagement therewith to provide support to the shell 40, and maintainthe shell at a predetermined distance from the inside of the wall 10.The fins 50 terminate inwardly of the rims 20 and 42 at 55.

It will thus be seen that a passageway 51 is provided in the interior ofthe tube 13 with which the mouthpiece 16 is in communication. Apassageway 52 is provided between the interior of the shell 10 and theexterior of the inner shell 40 for delivery of air toward the rim 20,and a passageway 53 is provided within the inner shell 40 for deliveryof air toward the rim 42.

The mode of operation will now be pointed out. The device is assembledas illustrated. A dish or container of a suitable liquid material of lowsurface tension such as aqueous soap solution and capable of formingbubbles is provided. The end having rims 20 and 42 opposite to themouthpiece 16 is dipped into the solution, coating the faces 22 and 47of rims 20 and 42 with liquid and which forms a film across the faces 22and 47.

The arm 31 is moved in the slot 17 to its rearmost position as shown inFIG. 2 to cut off flow of air to the passageway 53. The mouthpiece 16 isplaced to the mouth and air expelled into it.

The air passes through the whistle or siren 26 which emits itscharacteristic sound. The air then passes through the passageway 51 inthe tube 13, hollow cylinder 32 and passes out the slots 33 in thecylinder 32 and into and along the passageway 52. The air can escape inonly the direction outward of the wall 41 and between the outsidesurface 44 of the wall 41 and the inner surface 15, of the shell 10 byreason of the engagement of the rim 35 against the rim 41. The airforces out the liquid which bridges the faces 22 and 47 of the end rims20 and 42 thereby forming a large bubble.

The operator, when a bubble of the desired shape is obtained, manuallymoves the arm 31 to its most forward position in the slot 17. The slots33 of the cylinder 32 in this position are inside of the wall 44, andair is pre vented from flow into the passageway 52 because of the closefitting in the end opening of the shell 40 of the cylinder 32. The airmay flow only to and through the passageway 53. The air is forcedagainst the film of liquid which closes the opening 46 of the shell 40and forms many small bubbles continuing until the large bubble is unableto resist the outward urging and the adhesive action of the liquidretaining it on face 22 is overcome. The large bubble containing thesmall bubbles then floats off.

The valve 12 can be operated in the sequence as described or vice versa.Large bubbles alone, or small bubbles alone can be blown by movement ofthe arm 31 of the valve assembly 12 to the desired position.

I claim:
